Additional Notes

  • The 1988 BMW M5 utilizes 4x6 inch speakers in both front kick panel and rear deck lid positions, suggesting a uniform speaker size approach across the factory audio configuration.
  • Full-range speakers are specified for all locations, indicating these positions handle the complete frequency spectrum without dedicated tweeters or woofers in a component setup.
  • Kick panel mounting tends to provide different sound staging characteristics compared to traditional door-mounted speakers, potentially creating a lower soundstage origin point.
  • Replacing the rear deck lid speakers could contribute to improved rear fill and overall cabin sound coverage, particularly for rear seat passengers.
  • The 4x6 inch format, while less common than round speakers, may offer certain advantages in space-constrained mounting locations where rectangular configurations fit better.
  • Aftermarket full-range replacements in this size typically feature improved materials like polypropylene cones and rubber surrounds compared to period-correct factory components.
  • Given the age of the factory speakers, deterioration of cone materials and surrounds would likely affect frequency response and overall output quality.
  • The front kick panel location might prioritize replacement attention due to its contribution to primary stereo imaging and mid-range clarity for the driver position.
